EN 12368 is a European standard for traffic signal heads. Buyers should check the applicable edition, required performance classes and evidence for the exact product configuration.
What is EN12368?
EN 12368 covers visual, structural and environmental performance and testing of signal heads and optical units. Its scope includes red, yellow and green road traffic signals with 200mm and 300mm roundels. A reference to the standard alone does not establish that a particular product has passed testing.
Key Requirements of EN12368
- Luminous Intensity: Minimum and maximum brightness levels for different signal colors
- Color Specifications: Precise chromaticity coordinates for red, yellow, and green signals
- Beam Pattern: Light distribution must cover required viewing angles
- Environmental Testing: Check the environmental performance classes and the corresponding test conditions in the report
- Electrical Safety: Confirm the applicable electrical safety requirements and supporting evidence for the selected product
Why EN12368 Matters
Check the project specification and local authority requirements to determine the required standard edition, performance classes and conformity documentation. A certificate or report must match the model and configuration being supplied.
Other Compliance Information
- CE Marking: Required only where applicable EU legislation mandates it; it is not an approval issued by an EU authority
- RoHS: Restricts hazardous substances in electrical equipment
- IP Rating: Indicates protection against dust and water ingress
How to Verify Certification
When buying LED traffic lights, ask your supplier for test reports and certificates. Ask GAOQIAO for the documents applicable to the selected model. Check the model identification, issuing body, standard edition, test scope and declared performance. Confirm the applicable EU declaration of conformity and ingress-protection evidence separately.
Conclusion
Select products against the project requirements and verify the supporting documents before ordering. General website claims are not a substitute for model-specific evidence.
